ADOLPH BALLENBERG, OF NEW YORK, N.

CASTER.

household furniture and other articles of various kinds and classes in order to facilitate,the movement of such. articles from one point toanother; and the object of this invention is to provide an improved caster of this class designed particularly for use in said leg being composed of what is known as connection with metallic furniture, or furniture having metallic legs which are angular in cross section, or composed of what is known as angle iron. I

The invention is fully disclosed in'the following specification, of which the accompanying drawing forms apart, in whlch the separate parts of my improvement are des ignated by suitable reference characters 1n each of the views, and in which z- Figure 1 is a corner View of a leg of a piece of furniture provided with my improved caster; Fig 2 a section on the l ne 2-2 of Fig. 1; Fig. 3 a section on the lme 3-3 of Fig. 2; Fig. 4 a plan view of a blank from which a clamp attaching device which I employ is made; Fig. 5 a section on the line 5-5 of Fig. 3 and showing a modlfied form of clamp attaching device; and, Fig. 6 a plan View of a blank from which the clamp attaching device shown in Fig. 5 is made.

In the drawing forming part of this specification, I have shown at a oneleg of an article of furniture of the class specified,

angle iron, and having a cornera and two similar sides a I have also shown at b an ordinary caster, comprising the yoke member b in which the roller '12 is mounted'and the cross head portion b of which is provided with the usual pintle b.

In the practice of my invention, as shown Figs. 1, 2, 3, and 4, I provide'an attaching member 0 formed from a sheet 0 of metal shown in Fig. 4:, and said sheet comprises a central body portion 0 having a triangular side member a and a, rectangular side member a, and the triangular side Specification of Letters Patent.

A Application filed September 16, 1915. Serial No. 50,937.

member c is provided with an aperture 0 and is folded on the line 0 to form an inwardly directed triangular member 0 which fits snugly within the angle of the leg a as shown in Fig. 3.

The rectangular side member 0 is adapted to be folded on a linec and is provided with two folding lines 0 which divide the member 0 into a triangular body part 0 and two triangular corner members 0, and the body part 0 is folded inwardly to form the bottom form side clips which overlap the sides a of the-leg, as clearly shown in Fig. 1, and the central body part a of the rectangular side member 0 is provided with a central aperture 0 I The pintle b of the caster 2) passes upwardly through the aperture 0 and the aperture 0 and is'riveted asshown at b",- and this binds the caster to or in the attaching member 0, while permitting it to freely rotate therein, and the parts 0 which overlap the sides of the leg a have a spring action which securely clamp and bind the attaching member 0 to the leg, but which at the same time permit of the detachment from the leg of the caster, including the attaching member 0, whenever necessary, and

in this way I provide a caster which may be quickly and easily connected with the legs of an article of furniture, and which will re main securely in place while the article of furniture is in use, but which may also be quickly and easily detachedfor any purpose.

With my improvement no screws, bolts, rivets or other devices are .ne'cessary'to secure the caster in position, and the said caster when once applied, as shown and described, will remain in connection with the leg until it is'forcibly detached.

In the construction shown in Fig. 5, the clamp attaching device 0 is of slightly different form from that shown in Figs. 1,2 .and 3, and is made from the blank shown in Fig. 6, which difl'ers from the blank shown in Fig. 4 in that it is rectangular in form, and the triangular end portion a which forms the top part c of the spring attaching device is provided with supplemental triangular folding members 0 which are folded downwardly as shown in Fig. 5 to form supplemental clamp devices which bear on the inner walls of the side portions a of the leg or support, and with of the attaching member 0, while the triangular members 0 are folded to this construction the spring clamp devices 0 operate in connection with the spring clamp devices 0 to securely bind and hold the attaching member of the caster in the I caster to an angular leg, said caster being leg or support.

Although, I have shown and described my improved attaching device as particularly adapted for use in connection with what are known as angle legs or supports for various articles, my invention is not limited to this use in connection with the form of angle leg .or support herein shown herein shown and described, consistsof a.

and described, and my invention may be used in connection with legs or supports of other forms in-cross section.

F rom the foregomg description it will be seen that the attaching member 0,. as

back portion formed by the rectangular of the blank, an angular top body part 0 .portion which fits in the angle of the leg,

an angular bottom portion on which the leg rests, and the triangular spring clip or binding device which extend upwardly from the bottom portion, or upwardly from the bottom portion and downwardly from the top portion, and bear on the sides of the leg, as clearly shown, and described the preferred form of my improvement, my invention'is not limited to the exact details thereof, and changes therein and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit. of my invention or sacrificing its advantages, and it will also be apparent that my invention isnot limited to-the idea of connecting-the" caster with the attaching device by means of a pintle which passes upwardly through said device, and said device, and said caster may be connected with said attaching device in other ways. I

-I-Iaving fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The herein described attaching device for connecting casters with a furniture leg composed of angle iron, consistingof a back plate, a top plate which extends backwardly into the angle of the leg, a bottom plate in which the leg rests and upwardly directed clamping members connected with the bottom plate and which overlap the sides of the leg.

2. An attaching device for use in connection with an angular support, said attaching device being formed from sheet metal and consisting of a bottom plate on which the support rests, a back plate and a top plate, said bottom plate being provided with and while I have shown as my invention upwardly directed clamping members and said top plate with downwardly directed clamping members.

3. An attaching device for securing a provided with a pintle on which the attaching device is mounted and said attaching device consisting of a bottom plate on which the leg rests, a top plate connected with the bottom plate and which fits in the angle of the leg, and means for detachably securin said device in and to the leg, consisting o upwardly directed spring clamp devices connected with the bottom plate and which overlap the sides ofthe leg.

4. An attaching device for securing a. caster to an angular leg, said caster being provided with a pintle on which the attaching device is -mounted and said attaching device consisting of a bottom plate on which the leg rests, a top plate connected with the bottom plate and which fits in the angle of the leg, and means for detachably securing said device in and to the leg, consisting of upwardly directed spring clamp devices connected with the bottom plate and which overlap the sides of the leg, and other clamp devices connected with the top plate and operating inside of the leg. v

' 5. An attaching device for the support of an article of furniture or other article, said attaching'device consisting of a bottom plate on which the support rests, a top plate for detachably securing said-device in and to the support.

,6. A device of the class described for the support of an article of furniture or other article, said device consisting of a bottom plate on which the support rests, a top plate formed integral with the bottom plate and adapted -to be inserted into said support, spring tom plate and which overlap the sides of the support and other clamping members formed integral with said device for holding it in and to said support, said device being adapted to receive an attachment.

In testimony that I claim the foregoing I have signed my name in. presence; of the subscribing witnesses this 14th day of September, 1915.
